I've only worn a pair of the TBo underwear once so far. My initial thought is like I hope the size is right. Which it is a great fit. However after about a days wear, I thought that design should be more enhancing in the package area. Specifically I think I would have it so that the package should be lifted up more to support my low hangers. So it would be designed like a pouch that's lifted away from the body a tad. The material is very good quality. The seat should have a seam or pleat running down the middle to enhance the contours of the buttocks. Overall I am very satisfied with the merchandise.
